COVID-19 vaccines: How do the Moderna, Pfizer and Oxford coronavirus jab candidates compare?

Three trials of vaccines that will be available to the UK have all reported they are around 90% effective in late stage trials. The University of Oxford/AstraZeneca vaccine announced its phase three results on 23 November. It was the final of the three, with Pfizer/BioNTech the first to announce its results, followed a week later by Moderna, but that vaccine is still in trials.
